In the fourth in his series Dann, shows us the benefits of the paste command:

The paste command merges the lines of two or more files or a file and standard in if a second file is not specified or a "-" is used in place of the second file. Consider the following two files. The first file, test1.txt contains the following lines:

a
one
three
cat
good

The second file, test2.txt contains the following lines:

tuna
blue finch
dogs
fish
eats

The paste command can be used to paste these two files like so:

paste test1.txt test2.txt

producing the following output:

a         tuna
one     blue finch
three   dogs
cat      fish
good   eats

Each line in test1.txt has been “pasted” to the corresponding line in test2.txt.
